Item 1.01 Entry into a Material Definitive Agreement.

On April 24, 2013, US Airways, Inc. (the “Company”), Wilmington Trust Company, as subordination agent and pass through trustee under certain pass through trusts newly formed by the Company (the “Trustee”), Wilmington Trust, National Association, as escrow agent under the Escrow Agreements (as defined below), and Wilmington Trust Company, as paying agent under the Escrow Agreements, entered into the Note Purchase Agreement, dated as of April 24, 2013 (the “Note Purchase Agreement”). The Note Purchase Agreement provides for future issuance by the Company of equipment notes in the aggregate amount of $819,613,000 (the “Equipment Notes”) to finance the purchase of 18 Airbus aircraft scheduled to be delivered from September 2013 to June 2014 (collectively, the “Aircraft”). The payment obligations of the Company under the Equipment Notes are fully and unconditionally guaranteed by US Airways Group, Inc. Pursuant to the Note Purchase Agreement, at the financing of each Aircraft, the Trustee will purchase Equipment Notes issued under a Trust Indenture and Security Agreement (each, an “Indenture” and, collectively, the “Indentures”) with respect to such Aircraft to be entered into by the Company and Wilmington Trust Company, as indenture trustee.

Each Indenture contemplates the issuance of Equipment Notes in two series: Series A, bearing interest at the rate of 3.950% per annum, and Series B, bearing interest at the rate of 5.375% per annum, in the aggregate principal amount (once all the Equipment Notes have been issued) equal to $620,095,000, in the case of Series A, and $199,518,000, in the case of Series B. The Equipment Notes will be purchased by the Trustee, using the proceeds from the sale of Pass Through Certificates, Series 2013-1, Class A and Class B (collectively, the “Certificates” and each class of the Certificates, a “Class”).

Pending the purchase of the Equipment Notes, the proceeds from the sale of the Certificates of each Class were placed in escrow by the Trustee pursuant to Escrow and Paying Agent Agreements, dated as of April 24, 2013, among Wilmington Trust, National Association, as escrow agent, Goldman, Sachs & Co., Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, as representatives of the several underwriters, and Wilmington Trust Company, as pass through trustee and as paying agent (each, an “Escrow Agreement” and, collectively, the “Escrow Agreements”). The escrowed funds were deposited with Natixis S.A., acting through its New York Branch, under a Deposit Agreement corresponding to each Class of Certificates.

The interest on the Equipment Notes and the escrowed funds is payable semiannually on each May 15 and November 15, beginning on November 15, 2013. The principal payments on the Equipment Notes are scheduled on May 15 and November 15 of each year, beginning on November 15, 2014. The final payments will be due on November 15, 2025, in the case of the Series A Equipment Notes, and November 15, 2021, in the case of the Series B Equipment Notes. Maturity of the Equipment Notes may be accelerated upon the occurrence of certain Events of Default, including failure by the Company (in some cases after notice or the expiration of a grace period, or both) to make payments under the applicable Indenture when due or to comply with certain covenants, as well as certain bankruptcy events involving the Company. The Equipment Notes issued with respect to each Aircraft will be secured by a lien on such Aircraft and will also be cross-collateralized by the other Aircraft financed pursuant to the Note Purchase Agreement.

The Certificates were registered for offer and sale pursuant to the Securities Act of 1933, as amended (the “Securities Act”), under the Company’s automatic shelf registration statement on Form S-3 (File No. 333-181718) (the “Registration Statement”).
